Abstract

La présente invention concerne une limitation de l'accès à une mémoire par les applications au cas par cas, application par application. L'application reçoit un droit d'accès à une partie de la mémoire. L'application peut manipuler cette partie de la mémoire en y créant des structures de fichier distinctes, en modifiant, lisant et écrivant les fichiers qui y sont contenus. L'application n'a aucun droit d'accès à la zone de mémoire extérieure à la partie autorisée. De la même façon, les autres applications en mémoire dans la zone de mémoire respectent un paradigme similaire. Selon un mode de réalisation, la zone de mémoire est une structure de fichiers hiérarchisés, les applications étant en mémoire sous forme de fichiers fils de la structure de fichiers. Toutefois, les applications disposent de liens de correspondance indiquant les fichiers de la structure de fichiers dont elles dépendent pour empêcher l'accès à d'autres zones de la structure de fichiers. Selon un autre mode de réalisation, la structure de fichiers tient à jour un répertoire partagé avec lequel plusieurs applications disposent de liens de correspondance, également comme répertoire racine, mais pour un autre disque.
